Chapter 111 3 Standard Operation Procedures of Clearing BIOS Password and BIOS Recovery For RD and CSD to debug easily, the system provide a hardware gap for clearing BIOS password and a hotkey to enable BIOS Recovery. Clearing BIOS password If a BIOS Password (supervisor password and user password) is set for security reason, BIOS will check the password during POST or when entering the BIOS setup screen. However, if it is necessary to ignore the password check, a jumper shorting procedure must be performed on the gap. To clear the BIOS password: Note: Procedure below is used for clearing supervisor password and user password only. 1.Power off the system. 2.Unplug the power cable. 3.Remove the battery pack. See page 51. 4.Remove the lower cover. See page 53. 5.If necessary, remove the memory module. See page 53. 6.See illustration below to locate the hardware gap. RD/CSD can enable or disable this function by jumper shorting the G86 gap. 7.Using a eletrical conductivity tool short the two contacts on the hardware gap together. Refer to the gap setting on page 112. 8.While resting the tool on the two contacts, plug the adapter back in, then turn on the system. 9.After BIOS POST takes place, remove the tool from the switch. 10.Reinstall the memory modules and lower cover. 11 .Turn on the system and press F2 during the bootup to enter the BIOS setup screen. Repeat above procedure if the BIOS password is not cleared. Hardware gapDefault SettingOperation Description G86 Open (Normal) Short (To clear Supervisor and User password)
11 4Chapter 1 Recovering BIOS If BIOS flash fails in your system, perform a BIOS recovery procedure by using the crisis recovery diskette. During this procedure, the system will force BIOS to load and execute a special BIOS block (also called boot block) to restore the BIOS code from the crisis recovery diskette. Note the following when restoring the BIOS settings: TUse the Fn+Esc hotkey to enable BIOS recovery during BIOS POST. IMPORTANT:When using the Fn+Esc hotkey to enable BIOS recovery, we strongly recommend the following: tMake sure the battery pack is installed to the system. tMake sure the adapter is connected to the system and plugged into a wall outlet. TA crisis recovery diskette should be prepared in Windows XP. To restore BIOS by using a crisis disk: 1.Power off the system. 2.Connect a USB floppy drive to the system. 3.Insert the Crisis Disk to the floppy drive. 4.Press and hold Fn+ESC keys, then press power button. The system initializes the BIOS recovery process. The boot block BIOS starts to restore the failed BIOS code from the crisis recovery diskette. Once the process is completed, the system will restart. After a successful BIOS recovery procedure, RD/CSD can update the BIOS by regular BIOS flashing procedure.
